However, if the light source is close, glare may still occur. At this time, you can use your hand to block the light shield on the side where the light source is located. Whether the glare is eliminated, you must observe it clearly in the viewfinder This easy-to-use universal lens hood has a rear locking ring that allows the hood to be rotated in any direction to obtain the desired shading angle. Using a hood can help prevent flares (halos) in photos created from nearby light sources, resulting in higher quality photos.

They are one of the most important (but overlooked) accessories for improving the quality of photos. Package Include Lens Hood x 1 Note:The package only includes the lens hood, not the camera!
